also wanted to find out if the same option httpchk will work for https?
frontend http-5100
bind *:5100 ssl crt <cert>.pem
option httplog
capture request header Host len 24

server backUp05100r <serv2>:5100 ssl check backup verify none
Thanks,

Change get to GET, at least apache, ngingx and tomcat expect GET not get.
Or test with for example netcat that your server1 accepts get.
Something like: nc server1.add.re.ss 8093
get /nexus/v1/repository/rawcentral/com.att.swm.attpublic/healthcheck.txt
HTTP/1.1
Host: ...
Authorization: Basic ...

Like Jonathan said "No Host" is telling you what's wrong.
(HTTP/1.1 requests expect Host: header).
